Golf club construction



Filed Nov. 16, 1949 INVENTOR. ALBERT S. LIEBERS BY ATTORNEYS Patented Oct. 6, 1953 UNITED STATES OFFICE 1'. The present. invention..relatesto a golf club and particularly to a golf club having a weight thereinwhich serves to balance the clubhand'to' render *it "possible'by locating the weight to "improve a golfers stroke. For example, if a particular golfer is inclined to slice the ball the internal weight in the club may be placed in a position which tends to correct that fault.

The weight and method of incorporating it in the golf club is particularly adapted to golf clubs of the construction illustrated in my copending applications Serial Nos. 652,497 and 656,401 and now abandoned.

It is an object of my invention to provide a golf club having a weight incorporated within it, the weight serving not only to enhance the proper balance of the club, but also as a part of the actual structure of the club.

It is another object of my invention to provide a weighted golf club wherein the weight is incorporated in the golf club just prior to its final assembling and with the assurance that there will be no movement of the weight relative to the club at any time.

Other objects and features of my invention will appear when the following description is considered in connection with the annexed drawings in which:

Figure 1 is a perspective view of the golf club of my invention showing a cylindrical lead weight in the body of the club, the weight of course being illustrated in dotted lines;

Figure 2 is a transverse cross-sectional view of the golf club of my invention, the section being taken on the plane of the line 2-2 of Figure and Figure 3 is a view similar to Figure 2 but showing the portions of th golf club just prior to the final assembly operation.

Referring now to the drawings, the golf club ID, in accordance with my copending applications above mentioned, is formed of laminations II which have been molded with resins of the phenol formaldehyde type under pressure to thereby form. a very rigid, heavy, compact, wooden golf club. In the present instance, the golf club may be formed in two sections 12 and l3, or it may be formed as shown in the copending patent applications mentioned and thereafter severed to form the two sections l2 and I3. In either event the two sections are carefully bored out to form blind bores M and i5 which bores are accurately located and are of substantially the same size as the cylindrical weight l6, Figure 3, which is to be inserted therein.

2f Due-wtottheiact that; aswstated; thev bores l4 andLI5 areiofa size towaccuratelyofit. the cylindiical outline-of thehweight l6; thissweight acts as-a doweLandL'provides for. retaining. the accurate registry of the two sections I2 and I3 when they are assembled or reassembled with the weight l6 therein. After the two sections have been assembled, in the manner illustrated particularly in Figures 2 and 3, the two sections are joined by fusing the mating resin-coated edges under heat and pressure, this operation usually being performed by induction heating and serving to unite or reunite the sections I2 and I3 so that they become substantially one piece.

In addition, such heating serves to fuse the resin about the weight It so that the Weight is firmly held in its desired position.

The assembly of the weight into a golf club by the method above described provides a very superior club. In the past, clubs which were weighted were provided with a sole plate and the weighting material, usually lead, was poured into a cavity in the club and held in position by the sole plate.

As is obvious, the weight was almost invariably at the lower edge of the club whereas my weight is in the club and tends to yield momentum directly against the ball at the point of impact as it should.

Additionally, the area of the club on which the sole plate could be applied was limited and therefore the weight could not be located in a position such that it would tend to correct the golfers swing.

Furthermore, the sole plate being a separate element usually screwed to the bottom of the club could shift and the weight being held only by the sole plate could move about and become detrimental rather than beneficial. All of the above defects are obviously overcome by the mode of placing and holding a weight which I have invented.

While I have described a preferred form of my invention, it will be understood that the description was given solely for the purpose of illustration and that no limitations are to be made, the scope of the invention being defined in the claims granted to me.

What is claimed is:

1. The method of forming a golf club with a weight therein which comprises forming a body of phenolic resin, impregnated, laminated wood in two portions, drilling a blind hole in each portion, inserting a cylindrical weight in one said 3 portion, positioning said second portion on said weight as a dowel, and subjecting the assembled portions to heat and pressure to unite them into a single unit with the weight rigidly held therein.

2. The method of forming a golf club with a weight therein which comprises forming a body of phenolic resin, impregnated, laminated wood, severin the body to form two portions, drilling a blind hole in each portion, inserting a cylindrical weight in one said portion, positioning said second portion on said weight as a dowel, and subjecting the assembled portions to heat and pressure to reunite them into a single unit with the weight rigidly held therein.

3. A golf club comprising a body of laminated resin-impregnated wood and a weight entirely enclosed within said body, the body bein penetrated by a handle and its exterior surface being a continuous resin-impregnated wood surface, the weight extending transversely of said body and fitting tightly in a cavity in said body.

4. A golf club comprising a body of laminated phenolic resin-impregnated wood and a cylindrical weight entirely enclosed within said body, said body being carried by a handle and being 4 characterized .by having a continuous resin-impregnated external wood surface, said weight extending transversely of said body and the grain of the laminations thereof and fitting tightly in a cylindrical cavity in said body.
